NSI 5-HTP -- 100 mg - 120 Capsules

NSI 5-HTP -- 100 mg - 120 Capsules

5-HTP increases serotonin levels in the brain which may positively enhance mood, sleep and weight management! How does NSI® 5-HTP 100 mg work? 5-HTP, or 5-hydroxytryptophan, is a precursor to the neurotransmitter serotonin - which is essential for controlling mood, sleep and pain levels. The body produces 5-HTP from tryptophan, an amino acid found in small amounts in high-protein foods such as chicken, fish, beef and dairy products. It can also be taken in supplemental form, in which case it's extracted from the seeds of the Griffonia simplicifolia plant. 5-HTP is believed to help increase serotonin production in the brain, which may positively influence mood. 5-HTP may also help with other health issues related to serotonin deficiency, including nervousness, body tension and stiffness and head cavity discomfort. Certain elements of sleep are also believed to be affected by 5-HTP. Supplementing may not only assist with falling asleep faster, but also with increasing the duration of dream states (REM sleep) and of deep slumber. 5-HTP may also promote weight management by helping to reduce cravings for sweets and starches, which may help contribute to healthier overall eating habits. For best results and quickest absorption, take 5-HTP on an empty stomach. Do not take 5-HTP for more than three consecutive months without consulting a healthcare practitioner. NSI® 5-HTP 100 mg is better because it:. Ideal for supporting mood, sleep, and weight management. Is available at a better value than other 5-HTP products on the market.  . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

They say that you can sometimes dream a bit more/or maybe just remember more (I don't know), I don't seem to be experiencing this but my husband is for sure - makes for interesting morning conversation.... ha ha... I did meet with a RN/dietician for weightloss counseling and she recommended this as well. Hope this is helpful...."
